With the rapid development of China's electric power industry, the preventive experiment of electrical equipment is an important link to ensure the safe operation and maintenance of electric power system. Insulation diagnosis is an important means to detect insulation defects or faults of electrical equipment. The pointer type insulation resistance tester is a special instrument for measuring insulation resistance. JJG662-89 "Insulation Resistance Meter (megohm meter)" approved in May 1990 has been used as one of the mandatory verification instruments. At present, electrical equipment is developing towards the trend of large capacity, high voltage, structural diversification and sealing. This requires that the insulation resistance meter (pointer type) itself has the characteristics of large capacity, strong anti-interference ability, diverse measurement indicators, accurate measurement results, simple and rapid measurement process, and easy to carry.
Insulation resistance meter with ultra-thin wire head, a variety of voltage levels output, large capacity, strong anti-interference, AC and DC dual (type C), simple operation, with time prompt function. It is an ideal test instrument for measuring insulation resistance of transformers, transformers, generators, high-voltage motors, power capacitors, power cables, arresters, etc.
